IMPROVEMENT lN APPARATUS FOR HEATING SOLDERING-IRONS.

Specification forming part of Letters Patent No. 151,619, dated June 2, 1874; application tiled February 21, 1874.

To all whom it may concern:

Beit known tha-t I, GEORGE H. PERKINS,

of Philadelphia, Pennsylvania, have invented an Improvement in Apparatus for Heating Soldering-Irons, of which the following` is a specification The object of my invention is to quickly, economically, and uniformly heat soldering'- irons; and this I accomplish in the improved furnace shown in the vertical sections, Figures l and 2, of the accompanying drawing'.

In a trough, A, supported on legs a, is placed a casing, B, and within the latter is a central stationary spindle, supporting' an inverted circular cup, D, between the lower end of which and the easing B there is an open space. On the top of the inverted cup there is a plate, D', and between the latter and the cup are formed radial chambers mf, (best observed in the plan view, Fig. 3,) each chamber being, in the present instance, of a proper size for receiving a soldering-iron, x, which is provided with a handle, y, as shown in the perspective view, Fig. 4. In the inverted cup D and its plate D' there are openings q,(shown in Fig. 3,) through which the gases and heated air can pass upward into a hood, H, whence they are conveyed, through suitable pipes, to the external air. The side of the inverted cup is also perforated with' holes 1 at intervals, and the heated air and gases passing through these holes are directed upward to the hood by a beveled casing, I, on which the handles y of the irons may rest, and which prevents the undue heating' of said handles b v the iiames, which would otherwise be projected outward. The two burners consist of bent tubes G, contained within the casing B, and forming continu'ations of supplypipes G', which communicate with an elevated tank containing benzine, each bent tube having, near its closed end, a small hole, through which the vaporized benzine escapes in the form of a ame, which impinges against the under side of the inverted cup.

One of the irons x is placed in each radial chamber m, and, when all are sufficiently heated, one may be removed for use, and then returned prior to the removal of the next iron, the inverted cup admitting of being turned freely on the stationary spindle, so as to permit the removal of one iron after an other by the operative,who retains one posi tion near the furnace, and so as to insure the thorough heating of any iron which has been replaced after being used before it is again required.

One of the most important features of my invention is the inverted cup D, when viewed in connection with the burner or burners G. The llames impinge against the bottom of the said cup, and, in seeking an outlet, are directed downward and inward by the sides of the same, and again rise before escaping through the outlets q and r, as indicated by the arrows in Fig. l.

This I have ascertained to be the course of the iiame from thorough practical tests, to which I have submitted the apparatus, and the result is not only a nearly perfect combustion and an extended flame, of intense heat, from a comparatively small quantity of benzine, but the thorough heating of the cup D and its cover D', and, consequently, of the irons x conta-ined within the recesses m, the said irons being heated uniformly throughout their en tire extent.

I claim as my inventionl. The inverted cup D, arranged above the burners of a heating' apparatus, and having radial chambers m and vents q and r, all sub stantially as and for the purpose specified.

2. A soldering-iron furnace, in which are combined a casing, B, a burner or burners, G, and an inverted cup, D, having receptacles m for the object to be heated, and supported at a point directly over the said casing and burners by a central spindle, upon which the said cup can be rotated, all substantially as specified.

3. The combination, in a furnace for heating soldering-irons, of the inverted cup D, vents r, and inclined annular easing I, for supporting the tools and deiiecting the heated gases, as specified.

In testimony whereof I have signed myname to this specification in the presence of two subscribing witnesses. Y

GEORGE II. PERKINS.
